3.2.3  Transducer/buffer problems

Ultrasonic transducers are rugged, reliable devices. 

However, they are subject to physical damage from 

mishandling and chemical attack. The following list of 

potential problems is grouped according to transducer  

type. Contact Panametrics if you cannot solve a  

transducer-related problem.
• 

Leaks: 

leaks may occur around the transducer  

buffers and/or the flowcell fittings. Repair such leaks 

immediately. If the leaking fluid is corrosive, carefully 

check the transducer and cables for damage, after the 

leak has been repaired.

• 

Corrosion damage:

 If the transducer buffer material 

was not properly chosen for the intended application, 

they may suffer corrosion damage. The damage usually 

occurs either at the electrical connector or on the face. 

If corrosion is suspected, remove the transducer from 

the flowcell and carefully inspect the buffer electrical 

connector and the transducer face for roughness and/

or pitting. Any transducer damaged in this manner must 

be replaced. Contact Panametrics for information on 

transducers in materials suitable for the application.

• 

Internal damage: 

An ultrasonic transducer consists  

of a ceramic crystal bonded to the transducer case.  

The bond between the crystal and the case or the  

crystal itself may be damaged by extreme mechanical 

shock and/or temperature extremes. Also, the internal 

wiring can be corroded or shorted if contaminants  

enter the transducer housing.

• 

Physical damage: 

Transducers may be physically 

damaged by dropping them onto a hard surface or 

striking them against another object. The transducer 

connector is the most fragile part and is most subject to 

damage. Minor damage may be repaired by carefully 

bending the connector back into shape. If the connector 

can not be repaired, the transducer must be replaced.

IMPORTANT:

Transducers must be replaced in pairs. Refer to 

chapter 2, 

programming

, to enter the new transducer data into  

the meter.

If the instructions in this section fail to resolve the problem, 

contact Panametrics for assistance.
